Assume that our dye compound, XA, undergoes the following equilibrium in aqueous solution:
XA(aq) ⇄ X+(aq) + A−(aq) (Both X+(aq) and A−(aq) are colorless)
If a solution initially contains 30.4 μM XA and no X+ or A− prior to equilibrium, what are the concentrations of all three species if the equilibrium mixture gives an absorbance of 0.297 measured at a wavelength of 500.0 nm? Report answer in units of μM. (Hint: initial-change-equilibrium and you know some equilibrium information.)

3. The enzyme chymotrypsin is a protease that is competitively inhibited by a red dye. This protein and dye are combined in a solution and reach chemical equilibrium: protein + dye complex Prior to obtaining equilibrium and before any complexes have formed, the concentration of protein is G,o = 1.0 x 10-4 M and the concentration of dye is cd,o-2.0 x 10-3 M. (i) Write a simple expression that relates the equilibrium concentrations of protein cp and complex ce to...
